IMPROVEMENT IN MACHINES FOR SURFACE-SIZING, WADDING. &c.

Specification forming part of Letters Patent No'. 43,8194, dated August 23, 186i.

' 0 all whom it may concern:

Be it known lthat l, SAMUEL BAXENDALE, a resident of South Malden, in the county of Middlesex and State of Massachusetts, have invented a new and useful or Improved Machine for Sizing the Surface of Fibrous Bat- 1in g or Wadding; and I do hereby declare the same to be fully described inthe following specification and represented in the accompanyiug drawings, of which- Figure l is a top View, and Fig. 2 a longitudinal section, 4of it.

The nature of myinvention or improvements consists as follows-*that is to say, in the coinbination ot' a deiiector with the sizing apparatus and its brush, and with the machinery for supporting the bat or wadding, and moving it along.

1n thedrawings, A denotes the frame of the machine, within which there are two endless aprons,'B O, anda carrying-drum, D, arranged with respect to one another, as shown in Fig. 2.

Over the apron B there is a sizing-trough, E, within which there is a sizing roller, F, for transferring size from the trough to a rotary cylindrical brush, G, which is disposed over and so as to touch the roller F.

A stationary bar, H, extended across the frame A, is so arranged with reference to the brush GX that, while the latter may be in revolution in the direction denoted by the arrow a, it will cause the bristles of the brush to strike against the said bar and be bent backward by it, in order that, as the said bristles may pass by the bar, they may be sprung suddenly forward by their inherent elasticity, in

such manner as to throw sizing from their, and upon the upper surface otl the bat, as it may be traveling over the carrying-drum D.

In the operation of the machine the bat is to be moved along by the apron B, by which it is to be delivered upon the said drum D, which raises it upward and transfers to and upon the apron O, which is to aid in moving it along or carrying it toward a dryin groom or apparatus. Between the drum D and the brush G there is an inclined board or deflector, I, which extends upward from the inner edge of the sizetrough, and serves not 'only to intercept the surplus size that may be thrown oft by the brush, but also to break the current ot' airinduced by the brush, and cause part of it to pass downward toward the trough, while the rest of it may be passing over the upper edge of the deector, and carrying size upon the bat.

The endless aprons and the curved surface of the carrying-drinn are to travel at an equal speed. The brush is to be revolved independently of the trough-roller, which is also to have mechanism by which it may be rotated within the sizing-trough.

I claim- The combination of the deflector I with the rotary brush Gr, the sizing roller and trough, and machinery for supporting the bat and moving it along, substantially as specified.
